Embodiment 1
[0046] see figure 1 , which shows a communication device 1 provided by an embodiment of the present invention, the device 1 can be applied to a device, and the device 1 can include: a wireless charging power receiver 10 and a wireless charging power transmitter 20; wherein ,
[0047] The power receiver 10 is configured to send the first data to be sent to the power transmitter 20 through a receiving coil carrier according to a set transmission cycle;
[0048] The power transmitter 20 is configured to receive the first data to be sent, and check the first data to be sent; and,
[0049] After the first data to be sent is checked successfully, the second data to be sent is sent to the power receiver 10 through the transmitting coil carrier after a set interval; wherein, the time length T of the transmission cycle is greater than the set The preset interval time t1 is mentioned above.
[0050] It should be noted that since the two ends of the wireless charging need to realize the...
Embodiment 2
[0068] Based on the same technical idea of the foregoing embodiments, see Figure 4 , which shows a communication method provided by an embodiment of the present invention, the method can be applied to a home appliance, and the home appliance can include a wireless charging power transmitting end and a wireless charging power receiving end, and the method includes:
[0069] S401: The power receiving end sends the first data to be sent to the power transmitting end through the receiving coil carrier according to the set transmission cycle;
[0070] S402: The power transmitter receives the first data to be sent, and checks the first data to be sent;
[0071] S403: After the first data to be sent is checked successfully, the power transmitting end sends the second data to be sent to the power receiving end through the transmitting coil carrier after a set interval;
[0072] Wherein, the time length T of the transmission period is greater than the preset interval time length t1...

Abstract
The embodiment of the invention discloses a communication method, apparatus and device. The communication method can be applied to a household appliance. The household appliance includes a wirelessly-charged power transmitting end and a wirelessly-charged power receiving end. The communication method includes the steps: the power receiving end sends first to-be-sent data to the power transmittingend through a receiving coil carrier according to a set transmission period; the power transmitting end receives the first to-be-sent data, and verifies the first to-be-sent data; and after the firstto-be-sent data is successfully verified, the power transmitting end sends second to-be-sent data to the power receiving end through a transmitting coil carrier after a set interval duration, whereinthe time length of the transmission period is greater than the preset interval duration t1. Through the foregoing method, the technical solution of the communication method can avoid a communication conflict between the power receiving end and the power transmitting end during wireless charging.
Description
technical field [0001] The present invention relates to the technical field of household appliances, in particular to a communication method, device and equipment. Background technique [0002] Wireless charging refers to the wireless transmission of energy from the power transmitter to the power receiver, thereby eliminating the need for charging through a wired connection. The wireless charging technology is applied to the home appliance industry, so that it can supply power to the electronic devices and electronic devices in the detachable parts of the home appliance, and the structure of the home appliance is not limited by the connection. [0003] Taking the electric pressure cooker as an example, in order to effectively detect the temperature and pressure in the inner cavity of the inner tank, the current electric pressure cooker usually has a pressure detection device and a temperature detection device on the upper cover; and in order to provide power to these two dev...
